IMPROVEMENT IN HANGERS FOR SHAFTING.

Specification forming part of Letters Patent No. 156,636, dated November 10, 1874; application filed April 2, 1874.

To all whom it may concern:

Be it known that I, CHARLES E. HoLT, of Boston, in the county ot' Suffolk, State of Massachusetts, havel invented a certain new and useful Improvement in Hangers and Boxes for Shat'ting, of which the following is a description sufiiciently full, clear, and exact to enable any person skilled in art or science parts, as hereinafter more fully set forth and claimed, by which much better results are attained than with boxes and hangers of the ordinary construction.

The simplicity of my invention obviates the necessity of a lengthy description.

In Figure l, A B O D is the body of the hanger, and F the cross-bar or box-step, which is rendered vertically adjustable by the nuts` H and check-nuts G. The side pieces or arms D D are bent inwardly at the center in such a manner as to bring' the lower ends of the same into parallelism when the upper ends are attached to the beam A, as shown. The thimbles O O slide upon the inclined portion of the arms DD, above the central bend, and, with the part B, form an adjustable brace for strengthening the hanger. Each of the arms D, below the bend in the same, is threaded and provided with a nut, E, the lower side of which is conical in form, the upper side being dat. The box K is supported on the oval rest or pivot J, which is fitted to work in a corresponding concavity in the step F. Projecting centrally from the sides ofthe lower part of the box K there are two rounded flanges or lips, M I), Fig. 2, to which the cap of the box is attached by bolts passing through smaller anges, L N.

From the foregoing the nature and opera tion of my invention will be readily understood by all conversant with such matters. The box being in position in the hanger, as shown in Fig. l, may be readily adjusted vertically by means of the nuts G H, the pivot J being kept in its socket by the nuts E E, which when the box is in use, are to be turned dc w11 into contact with the ilanges M l?.

It will be seen that the conical formation of the lower part of the nuts E E and the rounded form of the flanges M P vallow the box to be swiveled on the pivot J, and to assume nearly any position necessary to accommodate itself to the shafting, the nuts, as they are turned up or down on the side pieces l) D, remaining in contact with the flanges and preventing the box from being thrown out of lits step, as will be readily obvious.

not bent to bring the lower ends of the same into parallelism, and are not provided with the adjustable step F or conical nuts E E, which are very essential features, the hanger herein shown being an improvement on said patented hanger in that respect.

I am aware that Letters Patent were granted to one Carey, April 8, 1873, and numbered 137,593, in which a hanger having vertical sides is described, and I therefore do no t claim anything shown or described in said Letters Patent; but

What I claim is- The box K, provided with the pivot J and flanges M P, and rendered adjustable,v by the nuts E E on the side pieces D D, substantiallly as and for the purpose specified.
